Technology

Overview

The AOD implant is comprised of a micro-porous membrane supported on a metal implant. The supporting frame for the AOD is fabricated from laser cut stainless steel tubing to allow low inflation pressure while maintaining optimal radial strength. The frame is completely encapsulated by an ultra-thin, porous polymeric membrane such that the interstices of the struts are webbed. The polymer used in Merlin’s AOD has gone through extensive biocompatibility and safety testing and enjoys broad market acceptance.

When placed and expanded in the parent vessel, the porous membrane serves to redirect blood flow from the aneurysm neck, thus occluding the aneurysm and reducing its potential for rupture. The porosity & pore-density of the membrane also allows flow to perfuse neighboring branch vessels that may be covered by the AOD.

The physicians have a better control of the overall shape of the implant, as they can post dilate (using Merlin’s PDB catheter) their way to a more conformable shape to the vessel.

Key benefits

  1. The AOD functions to divert blood flow from the aneurysm causing stasis and controlled thrombosis within the aneurysm. Cure for the disease, not a treatment for the consequence of the disease.
  2. Optimal surface coverage and pore density for immediate aneurysm occlusion while maintaining side branch patency.
  3. Flow diversion and geometric correction – eliminating shear stress on aneurysm wall. The AOD becomes incorporated into the arterial wall and becomes a definitive reconstruction of the diseased parent artery.
  4. Single device treatment, the aneurysm is immediately occluded with a single implant without the need of any adjuvant parallel implant or any coil support.
  5. Post dilation allows for a very conformable implant to the vessel wall, allowing for optimal blood flow within the blood vessel.
